Just like any other search engine, Ecosia shows ads next to its regular search results, so called EcoAds. These ads are text links to websites (i.e. businesses), which pay for each click by users. The ads are delivered to you by our partners Bing, who pay Ecosia a share of the revenue generated via these ads. Ecosia then uses at least 80 percent of its profits from said search ad income to plant trees.
